Using NiGUI, open a second window from main window

Both windows are responsive, but trying to tick a counter on the second window is a bit tricky

Using NiGUI, open a second window from main window

I copied the first example , then added the code of the second window I basicly created a second window by copying the code of the first window, then added the command to show the second window in the callback

Using NiGUI, open a second window from main window

However the second window is not interactive because it is not multithreaded. I am still figuring it out :)

sending to a channel before opening it doesn't create an error

Or is that impossible to check at compile time?

sending to a channel before opening it doesn't create an error

I have mistakenly, multiple times, sent items to a channel after initialising it but before opening it. The compiler never complained. After the program compiles and runs, it gets a SIGSEGV which I then discover my mistake. It would be very helpful it the compiler produced an error (like the typ

single line ref seq[int] assignment

var var1 = @[1,2,3] var2 = var1.addr --- the rest of the code--- Run I understand that this also works. Maybe too much time has been wasted on a minor inconvenience. But it is great that there are many ways to achieve the same thing Thanks for the help!

single line ref seq[int] assignment

I forget the brackets, my bad. I understand that sequences are heap-allocated. I wanted to have several variables point to the same sequence, so this is how I set it up. var var1 = new seq[int] var2 = var1 var1[] = @[1,2,3] var2[][1] = 2 Run

single line ref seq[int] assignment

I will preface this by admitting that it is only a minor inconvenience. However The official manual demonstrates creating a pointer variable and assigning a value to it (in var a3 line). type Student = object

pointer repr

In the official systems manual, and other tutorials online, pointer.repr prints the memory address of the pointer and the value it points to. This is a direct copy from var buf: seq[char] = @['a','b','c'] p = buf[1].addr

static checking of strings

I think this is what I was looking for I take it that it's not available now. Does RFC mean it's just a suggestion, or is it in planning / experimental ?

static checking of strings

Thanks for the reply I was trying to check for the rules at compile time (experimenting with type safety and such). While I understand that this method will work, it is not at compile time.

static checking of strings

I am experimenting with using concepts I am trying to enforce compile time checking of ipv6 import std/[setutils,strutils] type V4 = array[4,int] hexnode = concept a a is string a.len == 4 a.toSet < HexDigits V6 = array[8,hexnode]

static checking of strings

Ideally I would like for V4 and V6 to be strings with dots/colons but i figured getting the arrays to work is the first step towards that.

static checking of strings

as it stands, only `a is string` compiles when i uncomment the other rules I get a type mismatch error in hexno and loopback assignments

Trying multiple compilation settings in parallel

Thanks!

Trying multiple compilation settings in parallel

Thanks! It works now Even 2 threads in parallel affects the benchmark results a bit. * windows' antimalware service executable eats up more than 50% cpu utilisation in the parallel mode, so had to turn off windows defender This experiment was not very fruitful

Trying multiple compilation settings in parallel

Following my post a few days ago asking about which compilation settings to use for fastest throughput. I created a script that compiles the same file with different settings then uses hyperfine to check its performance. The first version (without parallelism) works just fine but is slow for tes

I will preface this by saying I just picked up nim 2.0.2 this week, coming from python and golang. I started experimenting with the nim.cfg setting to find the settings that get the fastest perfomance. This is how it looks now cc = gcc passC = "-flto -march=native -O4" passL
